BACKGROUND Few studies have evaluated predictors of childhood exposure to organochlorine pesticides (OCPs), a class of lipophilic persistent chemicals. OBJECTIVES Our goal was to identify predictors of serum OCP concentrations-hexachlorobenzene (HCB), β-hexachlorocyclohexane (β-HCH), and p,p-dichlorodiphenyldichloroethylene (p,p´-DDE)-among boys in Chapaevsk, Russia. METHODS Between 2003 an...

It has been shown that hypercholesterolemia (HCh) exaggerates the microvascular dysfunction that is elicited by ischemia and reperfusion (I/R). The objective of this study was to determine whether oxidants contribute to the exaggerated inflammatory responses and enhanced albumin leakage observed in HCh rat mesenteric venules exposed to I/R (10 minutes of ischemia and 30 minutes of reperfusion)....

In recent years, β-Hexachlorocyclohexane (β-HCH) has been detected frequently in water, seriously threatening human health and ecological balance. To explore the effects of different treatment groups on removal β-HCH experimental water response microbial community structure system, three strains β-HCH-degrading bacteria—Ochrobactrum sp. (Och1, Och2) Pseudomonas (Pse1)—combined with Canna were s...

Tar?msal amaçl? pestisit olarak hegzaklorosiklohegzan (HCH, C6H6Cl6) kullan?m?, tehlikeli olmas? nedeniyle art?k birçok ülkede yasaklanm?? olmas?na ra?men, günümüzde hala HCH stoklar? bulunmaktad?r. Bu noktada mekanokimyasal parçalanma (MKP) yöntemi izomerlerinin çevresel bertaraf? için büyük bir potansiyele sahiptir. Ancak bask?n (?, ?-, ?- ve ?-HCH) arada tatmin edici ?ekilde parçalanmas?n? s...

Staphylococcus aureusstrain HUK16 has been isolated from hexachlorocyclohexane (HCH)-long-term contaminated soil. The genome of strain HUK16 was sequenced to understand the genetic basis of its adaptation to HCH and to find the potential metabolic pathways allowing it to degrade the pesticide. Here, we report the annotated draft genome sequence (~2.7 Mbp) of this strain.

Sphingobium lactosutens DS20(T) has been isolated from the hexachlorocyclohexane (HCH) dumpsite in Lucknow, India, but does not degrade any of the HCH isomers. Here, we present the ~5.36-Mb draft genome sequence of strain DS20(T), which consists of 110 contigs and 5,288 coding sequences, with a G+C content of 63.1%.

Ralstonia sp. strain GA3-3 is a hexachlorocyclohexane (HCH)-degrading bacterial strain isolated from suburban soil in Canberra, Australia. The genome of strain GA3-3 was sequenced to investigate its ability to degrade α-HCH. Here, we report the annotated genome sequence of this strain.

In this study, we evaluate the long-term and seasonal variations of polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), α-, γ-hexachlorocyclohexanes (HCH), p,p′-dichlorodiphenyltrichloroethane (p,p′-DDT) its metabolites through a passive air sampling method at two (urban suburban) stations in Eastern Siberia, Russia, 2011–2017. The median levels HCB, ∑HCHs, ∑DDTs, ∑PCB39, ∑PCB6 were 116,...
